Очень маленький дистрибутив:

Требования: P-II, 128Mb RAM
"Thinstation runs on ordinary PC hardware (32/64 bit i686 class). You may either reuse older computers or save a lot of time on workstation administration. Or both! An old Pentium-II with 128 MB RAM or better can be a perfectly useful workstation. And you don't need a hard disk - you can boot off the network and even have a silent workstation. Workstation devices (floppy/HD/CD/USB) and printers (LPT/USB) are supported."
